  • Patent number: 11408006
    Abstract: Provided are: a method for preparing a DNA unit composition in which the mol number of a plurality of DNA units is more uniform, and a method for creating concatenated DNA. The method for preparing a DNA unit composition has: a step for preparing solutions which contain a plurality of DNA units to which an added sequence is linked, and preparing a solution for each type of DNA unit and a step for, after preparing each of the solutions, measuring the concentration of the DNA unit in each of the solutions in a state where the added sequence is linked to the DNA unit, and on the basis of the results thereof, fractionating each of the solutions and making the mol number of the DNA unit in each of the solutions closer to being identical to one another.
    Type: Grant
